VALLEY-TILE FOR ROOFING.

SPECIFICATION forming part of Letters Patent No. 430,368, dated June 17, 1890.

- ing drawings, in which Figure 1 is a plan View looking in a direction perpendicular to the angle of the valley of a roof, showing an assemblage of roof-tiles and valley-tiles underlapping. Fig. 2 is a cross-section of Fig. 1 on the line :0 00. Fig. 3 is a diagram referring to the relation of the form of the tile to the angle of the roof, here-,

inafter referred to. Fig 4 is an enlarged sectional view taken on the line y y, Figs. 1 and 2, looking edgewise to the plane of one slope of the roof. Fig. 5 is a plan view still further enlarged looking in a direction perpendicular to the plane of one slope of the roof, as indicated by the arrow in Fig. 6, and includinga portion of the tiles of said slope; and Fig. 6 is a bottom end view of the valley-tile, the same being drawn in project-ion of Fig. 5.

My invention relates to roofing-tiles of clay or other material, and it is applicable toitiles of approximatelydiamond shape laid in quincunx order.

My invention consists of a valley-tile bent to fit the angle of the valley and lying in overlapping series extending under the diagv onal terminal edges of such roof-tiles.

A feature of my invention consists in providing for a certain range of Variation in the position of said roof-tiles, while weather-proof joints are maintained between the same and the valley-tiles, irrespective of the amount of lap.

A A, Fig. 1, are the roof-tiles, and B the valley-tiles underlapping them to the extent a h under normal conditions. It is to be seen in Fig. 2 that the angle or bend given to the tile B is more obtuse than the angle (say the average) of the substructure C at the valley, the object being to insure against the Valley- 'tile bearing at its center and tilting in cases where the angle 0 d e of the substructure is greater. The outer portions of the valleytile are flat, as more distinctly represented in section of the eaves.

Fig. 6, so that the final diagonal course of the roof-tilesAmay occupy positions at greater or less distances from the center of the valley-tile without materially varying the pitch of said final diagonal course. an upwardly-turned flange e at its upper end and a down wardly-turned flange fat its lower end, wherebyitinterlocks with similar tiles above and below. The tile B also has upwardly-turned flanges g g at its two remaining sides forming continuations of the flange 6, whereby it interlocks with the downwardly turned flanges h of the roof-tiles. The upwardlyturned flanges g and the downwardly-turned flanges h do not necessarily engage adj acently with one another; but in all cases they form weather-tight joints, irrespective of the relative positions of the tiles A B. g

In order'to clear the upper portions 71. of the flanges h in all positions thereof, and also to adapt the valley-tile to other forms of rooftiles than those shown, an enlargement t' of the tile B is provided, bearing a part g of the flange g at an angle. The lower end of the tiles B bearing the flange f, and therefore also the upper end bearing the flange eto fit it, is made in whole or in part approximately parallel to the eaves of the roof-that is to say, the lower end may have an angular form each line lying parallel with the respective eaves at the terminus of the valley, and in tersecting at the center of the tile, or such linesmay be graduated together in a curve, as illustrated, tangent to the angle of inter- An object of this feature is to render the underlapping portions of the tile A parallel at top and bottom with the direction of adjustment of the tile A, as indicated by arrow in Fig. 5, in order to permit the more or less overlapping of the rooftiles and still maintain tight joints by the interlocking of the flanges thereof.

The feature of providing for a variable overlap of the tiles A upon the tilesB enables the valley-tiles to be employed in a common size or a very limited series of sizes for different angles of roof, such different angles causing the diagonal line of the roof-tiles A to lie parallel or unparallel in greater or less degree, as the case may be, with the roof intersection. For instance, referring to the dia- The tile B has gram Fig. 3, in which st to x represents a plan of a roof-tile of the character considered, and 'v w the angle of the roof, then when the length (or a half thereof t 1 of the tile bears the proportion to the breadth (or a half thereof 12 10) corresponding to that of the hypotenuse v 10 (equal to 25 0 in the diagram) of a right-angled triangle (to v w) to its base '0 u, in which the altitude u w is proportioned to the base 1) u as the altitude u w of the roof 1 w to its half-breadth 1; u, the diagonals of the tile A will be parallel to the hips and valleys of the roof. Under other conditions the angle of the diagonal edges it will vary more or less according to the departure from the above proportions, and will therefore require to be compensated for in the manner described.

\Vhat I claim as my invention, and desire to secure by Letters Patent, is

1. In roofing-tiles, a tile bent to lit substantially the angle of the valley, with its ends in whole or in part parallel to the line of the eaves, and extending beneath the tiles of the roof, having upturned edges whereby it interlocks with downwardly-turned flanges of the said roof-tiles, substantially as shown.

2. In roofing-tiles, a tile bent to fit approximately the angle of the valley and having the ends formed in whole or in part approximately parallel. to the eaves, substantially as shown.

3. In roofing-tiles,a tile bent to fit approximately the angle of the valley, with its ends in whole or in part approximately parallel to the line of the eaves, and with upwardlyturned flanges on its upper end and downwardly-turned flanges on its lower end, whereby it interlocks, when in place, the similar tiles above and below, substantially as specified.

4. In combination with roofing-tiles, a valley-tile with its ends in whole or in part approximately parallel to the line of the eaves, and having a portion extending beneath the adjacent roofing-tiles and forming therewith rain and wind tight joints.

5. In combination with roofing-tiles, a valley-tile, with its ends in Whole or in part approximately parallel to the line of the eaves, having portions thereof extending beneath the said roofing-tiles and interlocking therewith, and upward flanges at one end and downward flanges at the other end, whereby the valley-tile interlocks with similar tiles above and below and form rain and wind tight joints, substantially as described.

6. In combination with interlocking roofing-tiles, a valley-tile having its ends formed at an angle or curve approximately parallel or tangent to the angle of intersection of the eaves, whereby the roofing-tiles may be to a limited extent nearer to or farther from the intersecting line of the valley and still form wind-and rain tight joints with the valleytiles, substantially as specified.
